Hi I just experienced a kernel crash when trying to suspend my Lenovo Thinkpad T510 (model 4384-GJG) laptop. Normally I just shut the lid and the little moon icon lights up telling me that the laptop has suspended. This time was different; the moon icon didn't light up as it usually does, so I opened the lid again and found a kernel crash dump on the screen. The machine was completely dead at this point, so all I could do was take a photo of the screen - nothing had made it to the log files either (checked after a reboot). The image I took of the screen with the crash info is available here: http://personal.chaosbits.net/suspend-crash.jpg The kernel version is 2.6.39.3 The kernel config is attached as '2.6.39.3-config.gz' The distribution is Arch Linux 64bit. Here is a partial transcript of the image (typed in manually, so check the image if you suspect an error - I also left out function addresses/offsets and other details before/after the backtrace to save me some typing, so check the image for the full details) : Call Trace: ? wq_worker_sleeping schedule ? cfq_put_queue ? cic_free_func ? kmem_cache_free ? put_io_context do_exit oops_end die do_trap do_invalid_op ? free_msi_irqs ? find_busiest_group ? pci_conf1_write pci_disable_msi e1000e_reset_interrupt_capabillity __e1000_runtime_suspend ? __switch_to pci_pm_runtime_suspend ? pci_legacy_suspend_late rpm_callback ? schedule rpm_suspend ? linkwatch_do_dev ? pm_schedule_suspend pm_runtime_work process_one_work worker_thread ? manage_workers.isra.29 kthread kernel_thread_helper ? kthread_worker ? gs_change I've not experienced this before with this kernel, nor with earlier or newer ones, so it's not exactely reproducible on demand, so it's anyones guess when this was introduced (or if it's been there for ages, just triggers rarely)... One detail that may be relevant; normally when I suspend the laptop I do so before unplugging any cables or suspend after not having anything plugged in for ages (or at all). This time I was in a hurry, so I quickly unplugged the power, 3 usb cables and the ethernet cable and then quickly slammed the lid shut. Not sure if that has an impact on triggering this though. I tried reproducing that scenario 4-5 times, but the laptop suspended fine when I did that. If you require further information then please let me know and I'll be happy to provide it. I'll of course try to submit more details if it happens again, but if someone has a good guess as to how to provoke it or an idea for a fix I'd sure like to know. -- Jesper Juhl <jj@xxxxxxxxxxxxx> http://www.chaosbits.net/ Don't top-post http://www.catb.org/jargon/html/T/top-post.html Plain text mails only, please.
